I feel like an insect.
The reactions mentioned are like pheromones, passed between insects and animals. Humans sense them between each other too, but on a lesser scale.
[Logan]I was in a room that... it is hard to explain, but I received information about the woman within that I had not known. Her name among other things. I simply knew she had stolen the Hope Diamond and replaced it without her telling me so.
With the extensive information I carry about you and other mutants on board, I must know if you trust a woman named Parker.
Or if I must silence her I do not know what information she received from me.
I need farther instruction.
[Rogue]You do not know me, but I am
X-23 Laura. Logan trusts you, and has asked me to watch over you. So I offer any aid that you may need.
